Combine three almost identical synopsis lines into a single one,

and three almost identical entries in the options list likewise,
bcause all three have identical meaning and almost identical syntax.
While here, call the list of signals in signal(3) "complete"
rather than "more complete", because that's also true, a stronger
statement, and more concise.
